| ** Name: depend.c |
| ** Description: Test to enumerate the dependencies |
| * |
| ** Modification History: |
| ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag. |
| ** The debug mode will print all of the printfs associated with this test. |
| ** The regress mode will be the default mode. Since the regress tool limits |
| ** the output to a one line status:PASS or FAIL,all of the printf statements |
| ** have been handled with an if (debug_mode) statement. |
